Specify the client_id of the mqtt client

commlib/transports/mqtt.py

import paho.mqtt.client as mqtt
    def _connect_v3(self):
        properties = None
        self._client = mqtt.Client(
            clean_session=True,
            protocol=self._conn_params.protocol,
            transport=self._conn_params.transport,
        )

The underlying paho provides the client_id and wants to provide an interface to pass raw connection parameters to the underlying transport.
